It's when viewing a torrent listing on the site somewhere, yes? Where? Which view? In the details view of each torrent? When viewing a list, such as search results or latest torrents? Or absolutely everywhere? In all list view types (Grid, Legacy, Modern, etc.) or just one? Where and how is it showing these error messages? As a placeholder for each image? In the popup that's supposed to show several thumbs? As a page load error?

Could you provide more details of what the exactly the problem is? If you're able to add a screenshot or two that might make it much clearer.

Have you tried clearing your browser's cache? Viewing with a different browser? Rebooting your device? Another member was having a problem with images yesterday. Rebooting was temporarily clearing it, but the problem returned after a while. It was established (I think) that this was some sort of bug that needed work on. I don't know if that has yet been fixed. It may be related, or this may be an entirely different problem.
